Colin Patrick McCabe commented on HBASE-7636:
---------------------------------------------
I was not able to find any HDFS logs attached (but maybe I didn't look in the
right place?) If you can find where the test puts those, your answer is almost
certainly in there. And it's almost certainly a configuration problem.
In general, configuring short circuit reads is complex. For old-style
short-circuit reads, you need to set up special permissions on your DataNode
storage directories. You also need to specify the right user for
{{dfs.block.local-path-access.user}}. For new-style short-circuit reads, you
need to have {{libhadoop.so}} installed, and possibly be running with the
native profile {{-Pnative}} so that Maven will set up {{LD_LIBRARY_PATH}}
correctly. Then you need to set a valid socket path.
It's probably best to wait until we finish merging the HDFS-347 branch (vote
was successful, now we just need to do the work in svn), and then I'll help you
set up the conf for this test. You probably want to have a fallback for if
native code is not enabled.
